A series of recent studies have consistently shown that cannabis is not an effective treatment for common mental health conditions such as anxiety, depression, and PTSD. Reviews and systematic analyses emphasize the sparse evidence for cannabis as a therapeutic option, with many concluding that it may do more harm than good. Despite the popularity of cannabis among individuals seeking relief from mental health issues, scientists have debunked claims of its efficacy, stating that it rarely provides the expected benefits. The findings underscore a significant research gap, highlighting the need for more rigorous investigations into the effects of cannabinoids on mental health.
